My lume is far from perfect, or even good. It is passable and surely better from a distance! Practice. That's all it is. I've tried all sorts of tools to lume with, oilers and toothpicks and ultra fine brushes. Women used to hand paint lume on dials using a brush, licking the tip for sharpness and getting radiation poisoning in the process. I use a bamboo shish-ka-bob skewer for the round markers, flatten the tip, dip and one touch in the center of the marker. Being older than dirt, I need more help with the coronet and straight markers. I use a nib pen, which gives me better control. If you look at pictures of the gens taken back in the 1950s, they aren't perfect either. That is a clear benefit of replicating 60+ year old watches. They weren't perfect, nor cranked out by machines, but hand made with all the human imperfections. And I can do imperfections like an expert!
